Blender Intermediate Modelling Tutorial - Part 2: Boolean! 

You saved my life there haha Thanks!

thank you!

Thank you

Thank you

I couldn't seem to get the angle approach to line up. For me, I instead drew the line along the Z-axis by using K then Z

Thank you for sharing, was facing this problem and thinking what I did wrong.

Well hey I did the part 1 and when I did this part 2, exactly at adding a cylinder, when I select my anvil, the cylinder gets selected too and vice versa. If I delete the cylinder, my anvil also gets deleted and vice versa. I checked if it has been parented. But no! Even I did make sure that by clearing any parents made. Help me out. Though I only did that once and then I shut it down so I haven't tried twice or more. But do advice if you know the fix 🙏

Thank you so much!

Thank you! I just made the plunge from 2.79 to the newest version of Blender so I'm redoing these tutorials!

+AND REMEMBER TO INSTALL THE 2.91 VERSION OF BLENDER _ITS NOT AUTOMATIC_

Thanks a lot!!

Thank you !!!!!

thanks man. 👍👍

thanl you brooo

You are a genius. Thank you.

helpful!

Thank U!

You can actaully follow the last step of the tutorial (remove the bottom face and extrude the circle with snapping enabled (19:55) ) and that'll help too (also its easier)

Exact issue I was having, thanks!

exact same problem. thanks a lot!

thank you man

thank you

thank's for sharing! i knew somehow that the bottom face that not have the four vertices rule but I could not check if he had removed it so headache and more headache until I saw your comment ;)

Same problem! Thank you!

alt + m > b is the shortcut for a good measure

Thanks a lot! =)

Thanks a lot

Thank you!

Alternatively, selecting the edge and dissolving it (X -> dissolve edges) works too.

Many thanks

thx

Thanks

Thanks a lot

Epic

thanks, I had the problem with the subdivision surface :)

The vertices at the bottom of the feet of the anvil are sharp. The model seems to have put the edges right at those vertices instead of in the general area that the subsurf mod does. I don't know what I'm doing wrong.

Gosh, deleting the bottom face was the problem solver!! Thanks

Awesome suggestions! I never removed the bottom faces and doing that saved me. I was wondering why subsurf wasnt working. Appreciate it!

Awesome suggestion with the bottom of the angle, it helped the subsurface look on point!

dude, i had start over twice and i did not found the reason why. this just instantly fix the issue, thanks!

Thanks broo

This is what I needed. Thank you! Can somebody explain to me why this works?

I love you

YO thank you so much, i was getting weird artifacts when i applied the subsurf, it was caused by the face in between the mirrored side. deleted that and fixed it.

Thank you!

Thanks :)

Thanks for this! It was driving me crazy!

Hi i dont get how he did it i tryed like 14 times.... First when mu cylinder is target after modifier yeah my anvil "disapear" like we can see on the tutorial but when i pass in wire-mode for my cylinder i don't have the anvil cut form inside .. then when i pass in "difference" it's seems ok but just after when i go change "textured" to "wire" it show the cylinder and not the anvil with the form... and if i move a bit the cylinder its like all my previous actions are erased ( the booleen ) ... quit annoying (╯°□°）╯︵ ┻━┻ thanks, if you have any idea :> i'll appreciat

U ARE MY HERO

was struggling with this one too! but I found an easier way: First, Select the two vertices and press F on your keyboard to connect them. and then last step, double tap G to put the other vertex on the other vertex and then now you can emerge them (which is pressing M and by distance)

Thanks! this helped me a lot!

you're a frickin hero

Life saver, Thank you so much

scrolling by the "sort by new" to find this. perfect. works in 2.9 also.

@ I am getting a hole and face that arent anywhere near where they are supposed to be (where the original box was)

to clarify, on the wireframe, the edges are there but no vertices are attached and you cannot interact with them.

@@Finrii sorry I’m unsure as to where you mean you’re getting a hole? As in at the bottom of the anvil?

Worked, thanks a lot!

+Jona Wetter happy to know I helped

Thank you kind sir!

that worked! Amazing. i was in the phase of geting frustrated, but it's fixed for a while. Thank you!

+Csaba Gy. Woaw, couldn't imagine that my comment could help so many. Happy to help. Your answer reminds me to start again learning blender!

Laur CleverEdge and in the end even blender creates temporary triangles when it renders an image since triangles are rigid and precise and allow for accurate shading. But quads are kept for modelling purposes and phew ain't that a good thing :D

If all 4 vertices are in the same plane it would have been fine (older OpenGL had support for it even) but as soon as one of those vertices moves out of alignment you have to split it into 2 triangles, and do so in the correct manner. None of which is terribly hard, but if your trying to get the most out of your GPU for a game then it would be a waste to force the GPU to check all those quads (since it would have to check every quad, not just the ones that are broken). Much easier solution. Use triangles. All vertices of a triangle are guaranteed to be coplanar. So they dropped the support for it, if you want to model with quads you can convert the quads to triangles before rendering and deal with the headache yourself during development, most likely while exporting the model to the game engine.

But a computer doesn't know if the vertices are aligned unless it splits the quad into 2 triangles and calculates if the triangles have the same normal :P So triangles are still needed.

oh my gosh thanks for that info dude it spared me the trouble of an extensive research on Google but at least I know when to us tris or quads in models

I'd say you should always use quads when modelling. Converting to tris can be done when you export if the game engine can't use quads. But Unity and Unreal can interpret them at least. :)

Didnt delete the bottom at mine and got problems with the subsurface modifier because it wasnt a 4 point face. Spent almost one hour trying to find the solution

@@rodrigoromeu2789 underrated comment

any theory on why this is so? why his anvil didn't have a bottom?

Mine already had a bottom to, which messes up the subsurf because (if you look at the bottom view), there is just one big face with more that 4 vertices. Just align your view to bottom view and make the same kind of knife cuts along the bottom to split it up into a bunch of faces, all with 4 vertices.

@@smartestidiot2541 im guessing because he was using an older version of blender than most people watching at this point, which just does it like that automatically? I could be totally wrong though.

Ran into this and your comment helped! Thanks so much

I LOVE U ! THE COMMENT IM LOOKING FOR

Thank you!

Damn, thank you. I wondered why my base of the anvil broke apart after aplying subdiv on it. Cheers Man!

I love you. I was losing my mind.

Thanks a lot, saved me a lot of time scratching my head lol.

His face was so fun. xD

Same here

Update: I deleted the base of the anvil and it fixed it. I think he might have deleted his too. Thing is, the anvil looks ugly without a bottom now...

Haha Update 2: Yeah he deleted his base too, later in the tutorial he fixes that though.

Thanks a lot. :)

When did he remove the bottom face?

could you give a more in depth explanation on how to do so?

@@taahirsheik7918 Not the OP and I'm a beginner as well so take my advice with a grain of salt. The way that I applied his advice was by removing the face on the bottom of the anvil. Before you continue, turn on Snap during transform and snap to vertices. Then grab a vertice on the bottom wall of the anvil and press e to extrude. Lock it to whichever axis works best for you, in my case it was the y axis. Extrude and snap to a vertice to form a quad. Then select each of the four vertices by holding shift and clicking each one, and then press F to create a face. Then I went to the next vertice and repeated this process down the entire length of the anvil until I had 10 total faces on the bottom of my anvil, each of which was a quad. Once I applied my subsurface modifier it looked a lot cleaner and not like the pit you mentioned.

I solved the problem by doing Andrew's extrude operation on the bottom before I added the subsurf modifier. I don't know if this is easier than your suggestion, but it was relatively easy for me (a beginner).

Literally what i was about to comment 😁👍

Did you found out a good answer? I'm doing the tutorial and the dissolve option seems a little faster...

@@ricardoreis7298 seemed to screw up mine :/

@@ricardoreis7298 I went into edit mode, edge select, and then dissolved the edge and it worked out well.

Yeah, thats what I did. Seemed to be a lot less fiddly and faster! Though his method did introduce me to the magic of GG

Can you elaborate on this please?

doesnt work on blender 3.0

This helped me too, thanks.

My solution for keepin the base was to simply do what he did at the top - replace the single face with multiples that become part of the flow by creating new edges with the knife tool. After that you still need to add two more lines on each side of the base (with Ctrl+R) so the anvil doesn't curve at the foundation, looks rather silly that way. - Or you could just do what he does at the end and extend edges to create a new bottom face, which is way less work

I'm pretty glad I found your comment, because I had the same problem... Thanks!

thanks man, your comment saved my time!! even i was getting a vertex at the center of the curve outside the model which was visible in "face" mode only... so basically the easy fix is : delete the base face and then turn on sub-surf modifier... this did the trick for me :)

I knived my bottom to solve my problem, until I realized he did not have any base!

*LET ME GET A DRINK*

OMG THANK YOU! I WAS SO LOST

This did it for me

He is looking to the roof...

Without context "cutting through the face" would be a very unsatisfying thing.

Youre a life saver thanks

thanks . I stopped in that part trying to find the remove doubles in the preference

thanks man that really helped!

thanks this helped!

Thank you!!!

A year late to comment so things may have changed, but even rebuilding from a cube boolean does nothing for me when applied. I can see in x-ray mode that it's cut the curve out, but in object mode the anvil is still entirely intact.

doesn't work for some reason edit: selecting all before merging solved it thanks :)

@@beytullahberk3632 yeah, probably should have mentioned that

@@ValMephora he actually mentions it in the video lol i was just listening poorly

set the boolean modifier to fast instead of exact.

thanks

Thanks a lot mate, you've saved my day. I don't understand why it worked while previous option did not but I'm glad it did :)

no drop down menu appears. (im in Blender 2.83)

@@gargenall8161 yep they changed from alt +M to M

@@gargenall8161 just try M and i will pop up the menu

had the same problem, thanks!

Woah! Man, you saves ma anvil, couldn't work around it. I wonder what's the cause of it since it works for others with BMesh properly.

I was having this issue. Thanks for finding the solution.

I saw his worked just fine with BMesh as well. Very confusing.

same for me thanks

this one

works on blender 3.6 thx

Thank you! What is the purpose of these layers though? Why not just use a collection?

appreciate it

Thank you!

thanks

@Lucas Laborne your welcome brother.

I followed @Spos S advice in the above comments " What worked for me was removing the mirror modifier, and making the mesh "watertight" by adding a face to the back after deleting half the Anvil for mirroring. Select all the vertices around the faceless side and hit F. I had deleted the bottom face so I added that back in too, and then the Boolean op left the faces in. "

Tht's a great idea!

it may have to do with how the software is calculating the parametric boundary representations. the term boolean is used in every other 3d modeling software for any operation that calculates the difference between two "bodies", be they meshes or boundary representations.

I had the same thing :)

good sprit still working

same lol.

64 here... xD

Lmfaoooo

He told that in the first tutorial...
